The pakhangba is recognized by all groups a as national flag. The flag
adopted as a state flag in the short period of independence (1947-1949) is the
PAKHANGBA FLAG (national flag of Manipur, Snake Flag) in the red version. This
flag has been kept by the independentists as the national flag, to date. Jaume Ollé, 19 August 2003

Ziggiotto
(1998) shows an image of this flag - I think the proportions are 4:5. Jarig Bakker, 3 October 2003

The Manipur flag posted is as reported from TV images and is not the
princely state flag, but supposedly an independentist flag. But according to several sources this flag is (also?) used by
the Telegu Desam party that claims separation of Telingana from Andhra Pradesh and
might only be a mistake in attribution.Jaume Ollé, 8 June 1999

In Flags of Aspirant Peoples this flag is labelled as "Manipur (Meithei and hill tribes)". It is more likely a revendicative or separatist flag than an 'unofficial state flag'.Ivan Sache, 16 Sep 1999

This is not the official Manipur flag. The official flag is a symbol of 'Pakhangba,'
the mythical founder ancestor of the Meitei (not Meithei), and is an intricately
coiled snake. This was used before the take over of
Manipur by India in 1949 and is still in widespread use within Manipur. J.K. Parratt, 14 January 2002

"Consequent upon a
series of discussion forums, the one day national convention on identification
of State flags of ancient kingdom of Kangleipak (Manipur) held at GM Hall
yesterday took various decisions. The convention unanimously observed that
Pakhangba Pafal was found in most of the ancient flags collected from different
sources. It is also mentioned in the puya (ancient chronicle) found from
Ngariyanbam Kullachandra (Pandit Achouba). The convention further observed that
the flag used during the reign of King Khagemba was a complete flag which could
identify the land and did not have any outside influence. The convention also
resolved to hand over the task of publishing all the findings in a book to the
editorial board constituted on January 31 last."
